St Petersburg in Russia saw the smallest price increase in Europe, rising only 10% despite the sweeping sanctions in place – thanks to their domestic oil supply and refining capacity. Meanwhile, in London, motorists are paying 23% more for their petrol than last year – or £18.72 more for a 60 litre tank. As car owners across the UK feel the dramatic cost increase at the pumps, the most expensive petrol in the world is in Hong Kong at £2.26 per litre – up 39p per litre from a year ago. This is compared to £1.69 in London and £0.93 in New York. On the other end of the scale, Luanda, Angola and Tehran, Iran report the cheapest petrol at 0.24p and 0.07p per litre respectively.
